Filed: 1987-04-02
Abstract: A positron emission tomography camera having a plurality of scintillation crystal planes positioned side-by-side around a patient area to detect radiation there­from and forming adjacent rows of crystals transverse to the planes. Each row of each plane has a plurality of crystals and a row of light detectors are positioned adjacent each row of crystals. A row of slanting light guides are positioned between the crystals and the coacting detectors. The light guides are equal in number to the crystals and have a first end adjacent to one crystal and a second end positioned adjacent the detectors. The second ends of the light guides are axially offset in the rows a different amount from each other for pro­viding an identification to the detectors of which crystal detects radiation.

Abstract: A bunker (1) is provided with a conical bottom (3), with a discharge section (4) below the conical bottom (3), and with a closure member (5), for example a slide valve, at the lower end of the discharge section. An insert (6) is arranged in the lower region of the conical bottom, coaxially thereto. An annular gap (9) is provided between the interior wall (7) of the bottom and the exterior wall (8) of the insert. The interior wall of the insert is widened conically upwards in its upper region (10), and is substantially cylindrical in its lower region (11). A pipe (12) is coaxially moulded onto this lower region of the insert, encloses the lower region of the insert and is vertically displaceable thereon. Approximately at the transition (10, 11) from the conical to the cylindrical region, a second closure member (13), for example a slide valve, is arranged on the insert in order to control the flow rate of the bulk material through the insert. The upper periphery of the discharge section approximately coincides with the annular gap. The lower end of the pipe (12) is displaceable on both sides of the plane of the annular gap. The means for displacing the pipe and for adjusting the second closure member can be actuated from outside the bunker in order to adjust the flow rate as a function of the properties of the bulk material. <IMAGE>

Abstract: A frequency-compensated transistor feedback amplifier provides relatively wide bandwidth and relatively large phase and gain margins, irrespective of the transconductance of the transistors in the amplifier. The embodiment (10) includes a transconductance stage (20) and an amplifier stage (12 and 14). The transconductance stage delivers an input signal to the amplifier stage, which produces an amplified replica of the input signal. A feedback capacitor (24) connected between the output and the input of the amplifier stage provides dominant pole compensation by which the magnitude of the loop gain diminishes by 6 dB/octave with increasing frequency. The capacitor provides a forward feedthrough path for any residual portion of the input signal so that the residual portion arrives at the output of the amplifier stage in substantially the same phase relation with that of the output signal of intermediate frequency. This device can be implemented in circuitry whose input signal is taken from a transconductance stage that comprises an amplifier configured in either a single-ended output mode or a double-ended output mode.

Abstract: The gymnastic apparatus has at least one rocker pedal (1, 43', 44', 47, 50), which is arranged so as to be movable on a foot (5, 6, 46, 49, 57) and is coupled to a device at least for producing a pressing-down resistance. An apparatus of this type is to be usable in a person's daily routine in order, for example, to prevent weakness of the veins, varicose veins and wasting muscles. Since the complaints mentioned are widespread, an apparatus of this type must be inexpensively producible as a mass article and be very simple in construction and handling. At the same time, the risk of injury must be ruled out. It is proposed that the device for producing a pressing-down resistance is constructed as a leaf spring (9, 48, 55) which connects the rocker pedal (1, 43', 44', 47, 50) and foot (5, 6, 46, 49, 57) to one another at the heel end of the rocker pedal at a suitable angular position relative to one another. <IMAGE>

Abstract: A digital clock recovery system according to the prior art contains a phase sensor with a delay device. This cannot be implemented with the required accuracy in integrated circuit technology. The invention does not required any delay device for its implementation. A phase sensor (6) does not compare the phase relationship of the active edges of the pulses of a digital signal (DS) with a first auxiliary data clock (DHT1) which acts as clock recovered from the digital signal (DS), but instead, at phase sensor (6) compares the phase relationship of the active edges of the pulses of the digital signal (DS) and a second auxiliary data clock (DHT2) which has a defined phase difference relative to the first auxiliary data clock (DHT1). If the comparison does not result in a phase difference, a correction signal (K) is generated which causes a phase correction of both of the auxiliary data clocks (DHT1, DHT2) which produce the defined phase difference. Digital clock recovery devices are used in digital signal multiplexing devices and distributor multiplexors between, in particular, higher levels of a digital signal hierarchy.

Abstract: During the method for manufacturing masks with structures in the submicrometer region, structures (7) of photoresist (5) or polymer material having horizontal and essentially vertical side walls are produced on a silicon substrate (1) which is coated with an oxide layer (2). A layer of silicon nitride (8) is deposited thereon in a plasma deposition process. For the purpose of planarisation, a photoresist (9) is deposited on this structure and etched back until the start of the vertical flanks of the side wall coating is exposed by the nitride layer on the photoresist structures. A trimming mask (10) is produced on the surface of the nitride layer and planarising resist by a photolithographic method. The exposed regions of the nitride layer (8) are then removed by isotropic etching. The dimensions A-B of the apertures which are defined after removing the nitride layer from the vertical surfaces of the photoresist structures are transferred by anisotropic etching to the oxide layer. Simultaneously with these minimum line width structures, registration marks are produced which make possible the alignment needed for a further photolithographic process with the highest accuracy. After removing the trimming mask (10), the planarising resist (9) and the photoresist structures and the residues of the nitride layer, patterns are defined in a further photolithographic process which have a coarser line width and which are also transferred to the oxide layer (8). Using the oxide layer (8) as mask, grooves (11, 12) are produced down to a desired depth in the silicon substrate by anisotropic etching. The mask is thinned by oriented etching and oxide layers are removed from the front and rear side by wet etching.
